If you mean this Aug, you will have no chance to get those or likely anything else, including because you have not even purchased yet and if you purchased resale today, you won't even be able to reserve anything until a few weeks after closing when you get your member number, meaning you are likely looking at late August even before you can call to make a reservation.
If you mean on an annual basis beginning with August 2017 if you purchased today, then be aware that Poly and BLT lake view villas, all room sizes, as well as VGF 1BRs, dedicated 2Brs, and Grand Villas, have usually been open for any time in August at 7 months out when owners of other resorts can first attempt to reserve them. VGF studios and BLT standard and theme park view villas are often difficult to get at 7 months out for August.
